摘要

In this article we dimensionally reduce a heterotic supergravity on a G2 background with Minkowski spacetime using a certain cohomology as a basis for the Kaluza-Klein expansion, up to and including first order in α‵. We construct the moduli space heterotic G2 compactifications. The α‵-correction induces a curvature correction to the Weyl-Peterson metric. In the limit in which the G2 manifold reduces to SU(3), we recover known results.
